L-Arginine is a crystalline, free-form amino acid. It is an important factor in muscle metabolism and works to transport, store, and excrete nitrogen. It is a precursor for nitric oxide, which promotes increased circulation by relaxing blood vessels. It is also a precursor of guanidophosphate, phosphoarginine, and creatine, the high-energy compounds found in muscles.

This is a vegetarian formulation.

Jarrow FORMULAS Arginine + Ornithine contains only crystalline, pure free form amino acids. L-Arginine is a semi-essential amino acid synthesized by the body from Ornithine. Arginine and Ornithine support protein synthesis as they are involved in the transport and storage of nitrogen. Arginine, as a part of physical performance, is used by muscle tissue to produce creatine.
